Step‑by‑Step Instructions for Keto Peanut Butter Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (163°C). Meanwhile, line a baking sheet with parchment paper to prevent sticking. This step is crucial for achieving those perfectly baked Keto Peanut Butter Cookies, ensuring they come out soft and chewy. While the oven is heating, take a moment to gather all your ingredients for easy access.
Step 2: Soften the Nut Butter
If your peanut butter is not already soft, gently heat it in the microwave for about 15-20 seconds until it becomes runny. This will make mixing much easier and help create a smooth dough. Keep an eye on it to prevent overheating, ensuring it retains its creamy texture—this is key for your delicious Keto Peanut Butter Cookies!
Step 3: Combine Dry Ingredients
In a medium mixing bowl, whip together the almond flour, powdered erythritol, baking soda, and salt. Mix thoroughly until well combined, ensuring that no lumps remain. This is the foundational step that sets the stage for the incredible flavor of your Keto Peanut Butter Cookies, so give it a good stir and enjoy the aroma of your dry ingredients.
Step 4: Add Wet Ingredients
Pour the softened peanut butter and your choice of milk into the dry mixture. Using a spatula or a wooden spoon, stir until a thick dough begins to form, incorporating all the ingredients well. The dough should be sticky yet manageable; this balance is essential for creating those satisfying soft and chewy Keto Peanut Butter Cookies we all love.
Step 5: Shape the Cookies
Once your dough is ready, use your hands to roll it into small balls, about one inch in diameter. Place them on the prepared baking sheet, leaving some space in between each ball. Flatten each one slightly with a fork, creating the signature crisscross pattern. This not only shapes your Keto Peanut Butter Cookies but also helps them bake evenly.
Step 6: Bake the Cookies
Slide the baking sheet into the preheated oven and bake for 10 minutes. Keep a close eye on them; the edges should turn lightly golden while the center will look just slightly underbaked. This indicates that your Keto Peanut Butter Cookies are perfectly done, achieving that delightful chewy texture everyone craves.
Step 7: Cool the Cookies
After baking, remove the cookies from the oven and let them cool on the baking sheet for about 10 minutes. They’ll firm up as they cool, transforming from soft to chewy perfection. Patience is important here—allowing them to cool properly ensures your Keto Peanut Butter Cookies retain their ultimate deliciousness!

When you’re ready to bake from frozen, no need to thaw—just add a couple of extra minutes to the baking time! This way, you can enjoy warm, fresh Keto Peanut Butter Cookies anytime with minimal effort.

Keto Peanut Butter Cookies Recipe FAQs
What kind of peanut butter should I use?
Absolutely! For the best results, opt for natural, creamy peanut butter without added sugars or oils. This ensures your cookies stay keto-friendly and provides the right texture. If you want to switch things up, almond, sunflower, or pecan butter work beautifully too!
How should I store my Keto Peanut Butter Cookies?
I recommend storing your Keto Peanut Butter Cookies in an airtight container at room temperature for up to one week for maximum softness. If you live in a warm area or prefer a firmer texture, you can refrigerate them in an airtight container for up to two weeks.
Can I freeze these cookies for later?
Very! To freeze your Keto Peanut Butter Cookies, let them cool completely, then place them in a single layer on a baking sheet. Freeze until solid, then transfer them to a freezer-safe bag or container for up to three months. To enjoy, simply thaw them at room temperature!
What should I do if my dough is too sticky?
If your dough is too sticky, it’s likely due to the nut butter or moisture levels. You can add a bit more almond flour—start with one tablespoon at a time—until it reaches a manageable consistency. Remember, the dough should be sticky but not overly wet; finding the right balance is key!
Are these cookies safe for those with nut allergies?
While these Keto Peanut Butter Cookies are perfect for peanut butter lovers, they are not safe for those with nut allergies. Always check the labels and consider alternatives like sunflower butter, but be cautious as cross-contamination can still occur.
Can I adjust the sweetness of these cookies?
Yes, you absolutely can! If you find the cookies aren’t sweet enough for your taste, feel free to adjust the powdered erythritol to your liking. Just keep in mind that the moisture levels may change, so always start with small increments!
